Also it doesnt turn over unless l rev it and then go. Please help.

just sounds like you need to turn up the revs a little,,,,if its more serious than that l suspect its the mix in your engine,,but that still shouldnt cost more than 100quid

Hi
Being a qualified mechanic,i would suggest you check all your rubber vacuum pipes to your fuel system as if one of your pipes split you will not get the correct vacuum,which will cause the engine to stall

l have a W reg 306 aswell and Mine tends to TRY and do this but l have a performance air filter fitted, basically what l have noticed is when the car trys to cut out there is a gasp of air from the filter and it revs back up, Maybe its something to do with your air intake, im not very clever with cars but it just seems that my air filter saves it from cutting out.

l work for peugeot.
just a few questions first. does the trip milage reset to 000?
if so u have a fault with the ECU spiking the coil pack and the stepper motor(that controls the revs)
u have to buy all new parts if this is the case as they will do it again.
if not it sounds like the stepper motor is ckoked up with carbon and needs to be cleaned out. (most common)
u need a 20torx screwdriver and some carb cleaner.
